 the aperture, shining, and marked longitudinally with 

 fine, rounded strise. Whorls five, tumid, the last com- 

 posing about seven-eighths of the shell ; suture delicate, 

 not strongly impressed. Aperture two-thirds the length 

 of the shell, narrow lunate, somewhat dilated by the 

 moderate arching of the pillar margin, the lower third of 

 which takes the direction of the axis ; pillar margin 

 covered by a delicate lamina of white callus. 



Length of axis one and a half inches ; breadth four- 

 fifths of an inch.
